MyWorkoutCalendar: Free AI Workout Planner and Program Library

MyWorkoutCalendar is a free workout planning platform that combines an expert-curated program library, an AI workout generator, fitness calculators, and a workout tracker in one place. This article covers what the platform offers, who it's built for, and how to get the most out of it.

What Is MyWorkoutCalendar?

MyWorkoutCalendar lets you browse, generate, and follow workout programs in an interactive calendar format. Instead of reading a PDF or following a static spreadsheet, every program is presented as a week-by-week calendar showing exactly which exercises to perform on which days — and you can interact with each day to see the full session breakdown.

The platform is free to use with no account required for browsing programs. Creating a free account unlocks the AI generator, workout logging, and progress tracking.

The Program Library

The program library covers the most proven and popular strength and physique programs:

- **Push/Pull/Legs** — The high-frequency split for intermediate lifters - **Upper/Lower Split** — Evidence-backed 4-day split - **Full Body 3-Day** — Best for beginners and people with 3 training days - **PHUL** — Power Hypertrophy Upper Lower; combines strength and hypertrophy - **5/3/1 Wendler** — The classic percentage-based strength program - **Arnold Split** — Six-day split from Arnold Schwarzenegger's training era - **GZCLP** — Beginner-to-intermediate linear progression - And more

Each program page includes a full description, who it's for, how to progress, and an interactive calendar view of the full program cycle.

The AI Workout Generator

The [AI Workout Generator](/generate) creates a personalised workout program based on four inputs: 1. Your goal (build muscle, get stronger, lose fat, improve endurance) 2. Your experience level (beginner, intermediate, advanced) 3. Your available equipment (full gym, home gym, dumbbells, bodyweight) 4. Days per week (2–6)

The generator uses GPT-4o to create a complete, periodised program with exercises, sets, reps, and rest periods — structured to your exact specifications. No two generated programs are identical.

Free Fitness Calculators

The [Tools](/tools) section includes six free calculators:

- **One-Rep Max Calculator** — Estimate 1RM from any set; full percentage breakdown - **TDEE Calculator** — Caloric maintenance based on the Mifflin-St Jeor equation - **Macro Calculator** — Protein/carb/fat targets for cut, maintenance, or bulk - **Body Fat Calculator** — US Navy method estimate - **Plate Calculator** — What plates to load for any target weight - **Workout Volume Calculator** — Weekly sets per muscle group vs evidence-based landmarks

All calculators are free, require no sign-up, and provide instant results.

Workout Tracking and Progress

After creating a free account, the dashboard lets you: - Log every training session with exercises, weights, sets, and reps - View your workout history and progress over time - Follow a saved program with session checklists - Export any program or workout to PDF for offline use
